This invention relates to fluid discharge" nozzles, andhmore particularly. to a nozzle having an adjustable device arranged to produce a fluid stream which may be varied 111 5 character as desired. Nozzles of this general type are often used to discharge water at high'pressure inthe w'ashingof. automobiles, and it'is desirable that the nozzle deliveri either a concentrated flattened or spread into, a spray. Inthis service, the nozzles, are frequently thrown down .upon concrete floors, and otherwise roughly handled, and to be successfulthey must be capable of withstanding such treatment without damage. It is also desirable that the. adjusting'mechanism be simple to operate while the nozzle. is in use and so constructed as to remain in any given adjusted position until intentionally moved by the operator. V v It is accordingly. one object of my invention to provide an adjustable spray nozzle which isof simple butrugged construction 2 and which isfreefrom externally projecting portions liable to-become broken or dama 'edy It is a further object of my invention to provide a spray nozzle which may bej'easily and simply adjusted to produce either acoucentrated'jet or ardesi'red type of flattened jet or spray, and which willresistany accidental force. tending tochange 'theadjust meIit.

It is a further object of my invention to provide a spray nozzle whichmaybe adjusted'by the operator .without releasmg his grip upon the nozzle. 7

With "these and other objects-in view, as 40 willbe apparent to-those skilled in the art, my invention resides in the combination of parts setforth in the specification and covered by the claims appended hereto.

In accordance with my inventiorn'I' produce a concentrated'li'quid jet by any suitable means such as a circular orifice in a thin plate mounted at one end of a cylindricalpipe. In order to change this jet to a spraywhen desired, I provide a deflector which .is mounted near the orifice and spaced theresubstantially cylindrical jet or one which is to-the sleeve.

-i positioned as desired, means fisjpro vided whichcan be manually operated to .move the deflector to a desired position and t'oiholdit there in spite of the. force of the fluid jet, and 'for thispurpose, '1 preferably provide a member rotatable about an axisiparallel with the jet which is connected tofmove the deflector. In; the preferred constructiom:

the deflector is mounted for lateral movement within an extension on the nozzle, and the, adjusting device isa rotary-member, uch as a sleeve threaded on thenozzle, which may be easily turned; by the operator while -directing -the fluid stream against the object beingwashed. The deflectorillustra-ted in the drawings comprises a short bar or pin arranged-transversely of; the jetaxis and movable to or from the jet in guideways in a supporting structure mounted on ;the pipe. These .guideways may be formed as inclined slots in a sleeve, and the pin may be-adj usted a-long the slots by a member screw -threaded j Referring to thedrawings illustrating one embodiment of my invention, and in, which like reference numerals indicate like parts;

" providing a circular orifice 11in a thin cirof desired characteristics, Iprovide a de-' this may be conveniently accomplished by cular plate12 mounted at the end of the pipe with the orifice preferably coaxial with the p p -r In order t'ochange the issuing jettoa spray fiector which may be convenlently made in the form of a short bar or cylindrical pin 14:

arranged transversely of the jet "axis and preferably perpendicular thereto at a dis tance from the orifice 11 in the direction of flow. Thispin may bemounted ina suitable supporting structure or member such as a hollow cylindrical s1eeve15;., This sleeve is attached to' the pipe 10in any suitable manner; but is preferablyscrew-threaded to 1 the outside thereof as shown. f-The sleeve 15 may also serve to hold the orifice plate 1 2 in position against the en'cLof-thepipe 10.

Since it is 'desirabl that the deflector 14 be adjustable in relation to the jet so as'to permit it to {be moved from an inoperative position into-'the path thereofll provide suitable gui'deway's which may 'be conveniently formed as slots 17 in the sleeve 15. These slots 17 are mad'e o' f the p'r'o'per sizeto rece'ive the pin '14 and are preferably inclined a'ndJh'oldin-g= it securely' in axdesired adjusted positiom' anc'l this' is preferably: accomplished by means including ia 'rotar'y member mounted on the nozzle which I may be manually adju'sted "at will to a desired position here it Will stay until further a'dj us'ted. the-form illustrated, the bar 14isadjustablyipositioned by a controllingfor adjusting inember in 'the form of a hollow cylindrical outer sleeve 18, Which is threaded internally at 19 to fit screav threads 20 onthe outside ofthe finnensleeve "15. The threads 19 inside the sleeve 18 are a sleeve,

preferahly 'cut away at the 'rear end of the as shown at 21 in Fig. 1, in order'that the threads 20 may'remain "concealed by the outer sleeve at= all positions 1 "adjustment. This is desirable for the sakeof appearance,

; and to protect thethreads from iacci dental injury. It'wi'llbe understood that the member 18 vis 'adjustedlongitudinally? by rotating it relative to the inner sleeve, and this I adjustment may be facilitated by providing a knurledsurface '23 "on'the' outsideief'themember 18 as indicated in Fig. 2." Theouter sleeve 18 surrounds the pin 1& and thus prevents the pin from moving endwise out of the slots 17.

In order to communicate the longitudinal movement of the adjusting member to the deflecting' ba'r, I preferably so arrange these parts that the adjusting member contacts directly tvith the bar. This is preferably accom'plished by providing a proj'ection shown in the form of a-cylindrical sleeve 25, inte- Jgral With adjusting member 18 and extending inside the inner sleeve 15. A. large opening 26 is provided through theprojection 25 to permit free passage'oi' the liquid jet or spray.

. The deflecting bar 14 is held against the projection 25 byany suitable means, ssuchia'sa 1 coiled compressionlspring z27co=axial with V the nozzle and located between ithe bar .14

and the orifice plate 12. While the spring 27 :may bear directly againstthe pinpl l, I

prefer to provide a guiding cap 28 "arranged to'sli'de freely in the interior eflhe sleeved-5 andlocatedbetweeh the springand the pin.-

This cap has a .central opening -30 athere- 1 through which islarge enough in diameter to avoid interference withthe :jet.

The :operation of vmy invent' on zwillfnovv be apparentfrom the-above disclosure. Liquid under-pressure isbrought tozthe pipe 10 1-,

from a pump or otherv suitable source, and a concentrated jet issues from therorifice 511. By rota'ting the adjusting sleeve-18 relative to thevinner stationary sleeve 1'5,the pin 14 maybe moved rearwardly.alongthe=slots 7 1 against the pressure of spring 27 until2the pinclears the .jet entirely and the :jet [will issue Without any resulting spray. I By frotating the sleeve 18 in the other direction the pin. 14 may be 'broughtin'to: the path i of the jet and-the j et deiiected-intoa flat spray which may be varied in character as desired;

'The'pressureiof spring 27 increases-the friction at the threaded connection between the inner and outer -sleeves; -aand [thustends 'to prevent accidental alteration of the adjustment. The :nozzle is free"from ;externally projecting :parts, and. will withstand a. .considerable amount of rough handling with- -out inj ury. which is 'rotatable about "an axis parallel to the "jet, :may gbe conveniently grasped. with one'hand as the streamis-beingidirected'on the desired object and; may beeasily adjusted to vary the spray?without"theznecessity 0f l the operator releasing ;his gr.=ip: thereon.
